ROTARY CHURN..

SPECIFICATION forming 'part of Letters Patent No. 258,909, dated June 6, 1882, I Application filedFe'bruary 10, 1882. (No model.)

'City, in the county of Hardin and State of Iowa, have invented certain new and useful Improvements in Rotary ()hurns; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which, it appertains to make and use the same, reference being had to the'accompanying drawings, and to letters or figures of reference marked thereon, which form a partof this specification.

The object of my invention is to construct a churn which shall, first, be simple, durable, convenient, and easily cleaned, and, second, allow of no waste of cream when the lid of said churn is lifted, or when said cream is forced upward through the crevices of the churn.

My invention consists in the means used for attaining this object, as is hereinafter set forth.

In the drawings, Figure 1 represents a perspective view of the churn; Fig. 2,a sectional side elevation taken through thelinesww, Fig. 1; and Fig. 3 is a detail view.

Similar letters of reference indicate correspondin g parts throughout the drawings.

A represents the body of the churn, supported upon legs, and in plan shape an oblong rectangular parallelogram. The object in making the body oblong is to allow such an amount of space as that when the butter is thrown outward by the centrifugal force of the paddles it may collect in the ends of the body without interfering with the revolution of said paddles. The upper inner edges, a,of said body are beveled, for .the purposes hereinafter specified. Secured within the inner corners of the box, and flush with the same, are the prism-shaped corner-blocks B, said blocks being beveled upon their upper ends in order that the cream forced above said blocks may be returned to the bottom of the churn.v

Hinged to the edge of one of the endsof the body A is the lid 0. Said lid rests upon shoulders formed in the sides of the body at such a distance'loelow the upper edges of the same as that when the lid is closed its top shall be in a plane with the lowest part of the beveled edges (1. By this construction all the cream escaping through theinterstices around the lid 0 will be prevented from passing over the sides ofthe churn, and will be returned to the churn. Moreover, when the lid is raised during, the process of churning the cream which drops from said lid will fall upon the beveled edges and be returned to the churnbod y. This I consider a decided improvement upon the churns already patented, where such of the cream as drops from the edges of the lid escapes over the sides of the churn and is lost, while at the same time it bespatters and soils the outside of the box.

Attached to the top of the lid 0 are the brackets D E, which carry the working parts of the churn. These consist of a pinion, F, having a bearing in the lid 0. Through said lid the shaft passes and is rigidly connected with the spider G, the outer extremities of whose arms carry the paddles H. The latter are set at an angle of about forty-five degrees to the vertical plane of said spider-arms, this being found by experience to be their most effective position.

Gearing with the pinion F is the crownwheel I, carried by the shaft K. The latter is journaled in the upper extremities of the brackets D E, and bears upon one end-a crank-handle, L, by which the paddles are operated.

M is a rest for the-lid of the churn when said lid is raised for the purposeof cleaning the paddles.

N is an air-vent passing through the lid G and connecting with the inside of the churn.

By the aforegoing construction it will be seen that while the butter is being formed the action of the paddles is not interfered with; that no wasteof cream is possible, either while churning or when the lid is raised, and that the whole machine is easily cleaned, exceedingly simple, effective, and little liable to fall out of repair.

Having thus described my invention, what I claim is-- 1. In a rotary churn,'the combination of the oblong rectangular churn-body A, having its upper edges recessed and beveled, with the lid 0 and the corner-pieces B, beveled upon their upper ends, substantially as described, whereby when the lid is raised or the cream is driven upward through the interstices about the edges of the lid said cream is returned to the ehurnare prevented from collecting in the corners, body, and whereby the cream is prevented from and whereby the churn may be easily cleaned. 1o collecting in the corners of the churn, and In testimony whereoflafiix my signaturein thereby retarding the formation of the butter. presence of two witnesses.
